At the beginning of a science experiment, the temperature of Darnell's saltwater solution was

Question

–
2°C. During the experiment, the change in the temperature of the solution was
–
5°C.
What is the final temperature of the solution?
°C

Answer 1

To find the final temperature of the saltwater solution, you need to add the temperature change to the initial temperature.

The initial temperature is –2°C, and the change in temperature is –5°C.

Calculating the final temperature:

\[ \text{Final Temperature} = \text{Initial Temperature} + \text{Change in Temperature} \]

\[ \text{Final Temperature} = -2°C + (-5°C) \]

\[ \text{Final Temperature} = -2°C - 5°C = -7°C \]

The final temperature of the solution is –7°C.
